Organic fertilizer :-
According to
Wikipedia , organic fertilizer is derived from animal matter human matter and vegetable matter naturally occurring fertilizer include animal waste from meat processing peat manure slurry and guano.
A naturally occurring fertilizers which include manure, slurry, worm casting, seaweeds, and guano and are naturally enzyme- digested proteins, fish meal and feather meal, decomposing crop residue from prior is another source of fertility.
different type of organic fertilizer :-
There are three main major type of organic fertilizer are :-
- Animal source
- plant source
- minerals
1. Animal source :-
- manure
manure are animal wastes that are used as a source of plant nutrients. animal waste like cow dung and urine. they release nutrients after their decomposition. manure improve the fertility of the soil by adding organic matter and lots of nutrients.
major source of manure:-
farmyard manure refers to the decompose mixture of dung and urine of farm animals . the waste products contains a wealth of nutrients, including the extremely important element that plants need nitrogen.
It contains 0.5% nitrogen 1% of phosphorus and 0.5% potassium.
farmyard manure is valuable soil improver which enhance and restores a range of natural properties of the soil; increase soil fertility.
The sheep and goat manure contain a higher nutrients than farmyard manure and compost. the manure refers to the decompose mixture of sheep and goat dung and urine.
the sheep and goat contains 3% nitrogen ; 1% phosphorus and 2% potassium.
It applied in the field in two ways :- the sweeping of the sheep or goat shed are placed in th pit for decomposition and uses later in the filed .
the second method the waste material kept in th field overnight and mix with field with the cultivator.
the manure consist of the poultry waste . poultry manure contains higher nitrogen and phosphorus compared to the farmyard manure
the poultry manure consist of 3.03% of nitrogen ,2.63% of phosphorus,and 1.4% of the potassium.
2. Bone meal
Bone meal is made up of crushed animal bones. it contains phosphorus and calcium and supplies sone nitrogen. It can promote plant seedling growth and increase yield.
3. Fish emulsion:-
the decomposition of fish delivers a big dose of nitrogen. it act as soil conditioner and also be carefull, because it cause acidic to the soil.
2. plant source :-
the plant based fertilizer are those fertilizer which are produced to the decomposition of the plant waste and provide nutrients to the soils
- compost
compost is the organic fertilizer which is produced to the decomposition of the kitchen waste and yard waste an helps in the improve soil structure , provide a wide range of nutrients to the soil.
it contains 2% of nitrogen, 0.5% phosphorus and 1% of potassium.
.
2. green manuring
green undecomposed material used as manure is called green manure . A green manure crops can be cut and them plowed into soil or simply left the ground for an extended period prior to tillage garden areas.
the green manure includes grass mixture and legume plants.
3. mineral fertilizers ;-
1.Rock phosphate
phosphate is extracted from mineral rocks and clay. it can be used to increase soil acidity and promote plant seedling growth.
2. Green sand
Greensand is an olive -green sandstone containing glauconite. it is rich source of iron, potassium, and magnesium. it aids in the stimulation of flowering and fruition in the fruit trees. and also increase the water content in the soil improve the rhizoshere.
